You're looking through Oxygen
to read this!

UT the gas your eye pierces—the gas you inhale at every
breath—is but the raw material for Linde Oxygen.

Every trace of physical contamination must be eliminated, every
chemical impurity removed before atmospheric oxygen is pure
enough to meet Linde requirements.

To that end a great army of Linde scientists are constantly at
work rigidly maintaining the high standard of Linde purity. To
their efforts is due the absolute uniformity for which Linde Oxygen
is famous.

will mark an epoch in the number of marine events, hap- -

C6 A MERICAN Marine Week,” November 14 to 19, inclusive,

pening simultaneously, which are of interest to the ship-
ping and shipbuilding industry. But this is not all, the public will
be given a chance to see, through exhibits and lectures at the
Marine Exposition, how important our merchant marine actually
is to our national prosperity.

The Marine Exposition, which will be held under the auspices
of the Marine Equipment Association of America at the Central
Mercantile Building, Sixth Avenue, 18th to 19 Streets, New York
City, will be open throughout the entire week. Practically every-
thing of interest relating to shipping and shipbuilding will be
exhibited. Professional men will have an added inducement to
attend the convention of the Society of Naval Architects and
Marine Engineers. Practical men will have the opportunity to
inspect models and full sized pieces of equipment. The buyer and
the seller of everything that goes into a ship will have a chance to
get thoroughly acquainted.

The convention of the Society of Naval Architects and Marine
Engineers will be held on November 17 and 18. On the afternoon
of the 17th there will be a joint session with the Institute of Elec-
trical Engineers, and on the evening of the 18th the annual ban-
quet at the Waldorf-Astoria.

The American Society of Marine Draftsmen will also hold
their convention during the week. This is an enthusiastic body

of men whose influence is bound to be felt in the shipbuilding of
the future. The coming gathering will mean much to them, both
from a social and from an educational standpoint.

Arrange your plans now to be in New York during the big
“American Marine Week.” The Marine Equipment Association
of America, of which K. L. Ames, Jr., McCormick Building, Chi-
cago, is secretary, will do its part. How about You?

ROM the sailing ship of earlier days to the specialized, oil-burning, steel cargo-carrier
of today; through all its ups and downs to its present outstanding position, the Ameri-
can Merchant Marine has fostered and will maintain those traditions which enrich the

history of sea transportation.

For nearly a quarter century, the New York Shipbuilding Corporation has contributed
of its skill and its ideals to the upbuilding of that which is best in our merchant and naval
fleets of today. The largest single unit in America’s shipbuilding capacity, New York Ship
started unhampered by limitations of physical layout or inherited practices. Its founders
had the vision and the ability to pioneer in the adoption and development of many ship-
building methods now accepted as standard by all.

These ideals have been steadfastly maintained; and upon the foundation of complete

| 13 plant facilities and modern steel-working practice there has grown up a tradition of accom- ¥ |

| plishment in the building of good ships—ships that proudly take leadership in the greater

American Merchant Marine, that reflect New York Ship’s

Accurate
Boring f
Methods

HE presence of excessive noise in a reduction gear means waste
of power and ultimate deterioration of the wearing parts. To
eliminate noise, gear teeth are machined with extreme accu-

racy. /\ccurate tooth form and spacing is folly if the gear and pinion

are not supported in perfect alignment. The Terry method of boring
the gear case (shown above) insures perfect alignment and an accu-
rate distance between centers. A glance shows how simple it is to
check the boring for perfect parallelism and correct center distance.
This accuracy of boring would again be folly if the construction of

the case did not maintain this accuracy after it had been once es-
tablished.

Bulletin S-171 can be read in five minutes. It explains all the problems
of the simplest Reduction Gear. Write for it.

MARINE
SUPERHEATERS

The Foster Marine Superheater for both Scotch

a steel tube with cast iron rings. This construction

will withstand greater temperature changes than a
bare steel tube and will maintain steady superheat.

It is not necessary to flood Foster superheaters,

no repair cost. About once a year the superheater
should be opened up for an internal inspection and
cleaning if required due to boiler priming.

The soot blower should be used to clean the
superheater surface externally once each day. Su-
perheated steam should always be used for the soot
blower.

There is probably no other part of the marine

and has as small a cost of repairs and operation as

Oil Burning System

In the Bethlehem (Dahl) Mechanical Fuel Oil Burning
System, low fuel oil consumption is obtained by correct
design of the burner parts based on an intimate knowl-
edge of the requirements of oil burning.

By means of the positive control on the furnace front,

the air supply is regulated to give the proper volume for
perfect combustion.

Low fuel oil consumption, simplicity of operation, low
first cost—are characteristics of the Bethlehem (Dahl)

system.

The Importance of Good Rope

Millions in property and thousands of lives are trusted each year to
a single line of Whitlock All-Manila Rope. Such is the confidence,
born of long experience, that sailors place in Whitlock Guaranteed
Cordage—and sailors know rope.

WAIMLOCK @ORDAGE

THE UTMOST IN ROPE VALUE

On land as well as at sea, rope users are swiftly learning these three

vital facts about Whitlock All-Manila:

It actually costs less because it lasts much longer than cheaper grades.
It retains its great strength long after cheaper grades have become weak and unsafe.
It will stand up under the hardest tests of wind, weather and work.

Men who have learned these things seek the dealer who carries
Whitlock Products. You should be one of these dealers.

Write today for a catalog describing our complete line of Manila and
Sisal rope and twine. Ask, also, for the Whitlock distributor in your

CUTS RUST!

The product that is destined to save billions of dollars yearly in connection with metal repair
work in Shipbuilding and Repair Yards, on Board Ship, Railroads, Automobiles, and Trucks,
Farm Machinery, Plumbing, Construction Work, etc.

On Board Ship And in the Drydock

The High Cost of Rust

has been a most difficult problem to overcome

In the Shipyard

RUSTSOLVO—the liquid which cuts rust—will reduce this cost to a minimum. A small quan-
tity of RUSTSOLVO applied to a rust bound bolt will so soften the rust that a child can turn it.
Rust on plates which have been exposed to the elements is softened in a like manner and the work
of removing it with a chipping hammer is materially lessened.

ONSIDER the tremendous forces required to drive a great mass
of steel through the heavy seas and the great stresses involved as
the propellers bite into the waves, steadily pushing their heavy burden.

To carry a great boat to its destination without accident, or unnecessary
delay, dependable equipment is required—not only strong shafts,
propeller blades and reducing gear, but uniform, strong, dependable
boiler tubes.

Great strength and other inherent advantages make “SHELBY”
Boiler Tubes highly dependable in carrying the high pressures of

One of the six effect Lillie Evaporators installed on the U.S.S. Tennessee
and California for supplying distilled water

Distilled Water at Minimum Cost

HE Lillie Evaporators have made possible greater economies

' in distilling sea water on U. S. Naval vessels than were ever
before obtained. This is partly because the evaporation is from

thin films of sea water enveloping the tubes, thus utilizing all of the
temperature drop from transmitting heat. Exhaust steam or other
low pressure steam can be used to operate multiple effects. The sex-
tuple effects on the U. S. S. TENNESSEE and CALIFORNIA

are notable examples.

Distilled water produced by the Lillie six effect apparatus on
the Battleship Tennessee was considered extremely pure. The six
effects were operated as two triple effects simultaneously, as a rule.
The average salinity from the two during the trial runs was about
Y grain per gallon, which contrasts with the contract limit of 2
grains per gallon. One of the triple effects was especially equipped
to'reduce salinity. The test of this triple effect by itself showed less
than 0.05 grain per gallon.

The problem of incrustations is also solved in Lillie Evapora-
tors by vapor reversal. Not only is the process of evaporation nearly
continuous, but there is little falling off in rated capacity.

Many other interesting features of Lillie Evaporators for

marine work are described in our Lillie Booklet, “Distilled
Water for Boiler Make-Up Feed” and in our Bulletin 114.

See our exhibit at the Seventh National Exposition of Chemical
Industries, New York City, during the week beginning September 12th.

Boyers balk the chalker

HE trail of perfectly-driven

rivets in the wake of Boyer-
equipped riveters makes rivet
inspection a “light occupation ”*
indeed! And cutting out improp-
erly driven rivets is an expense
worth avoiding.

Sustained driving power and
day-in-and-day-out dependability is
the only straight-through road to
100% steam or air-tight rivets.

Long after other hammers have
been ‘‘stepped down,”’ Boyers are
still hard-hitters. Backed by the
durable Boyer valve—the valve case
with five lives — their giant driving
power is as everlasting as the
hammer itself.

The hardest-hitting, longest-
lasting hammer you can buy is the

Boyer. Ask for Bulletin 600.

Dé Laval Oil Purifiers are furnishing better and more eco-
nomucal lubrication on more than 700 ships, including some
300 vessels of the U. S. Navy.

‘“‘The Texas Company approve the use of the
De Laval to maintain our oil in a clean condition’ —

—says Chief Engineer Lonigan of the S.S. Alloway. The
Chief knows and the Texas Company know that the De
Laval Oil Purifier increases the working life of any good
oil. It purifies the used oil by centrifugal force, instan-
taneously removing the water and other foreign substances
which find their way into the oil as it circulates through
the lubricating system. It returns the used oil to the lubri-
cating system with its efficiency equal to that of new oil.

Every reputable oil company is a booster for the De
Laval Oil Purifier. It guards against poor oils by throw-
ing out the heavy adulterant that sometimes fools the eye.

Increase the life of your lubricating oil. Protect your-
self from cheap substitution. Send today for Crank Case
Oil Bulletin No. 102, or for Marine Bulletin No. 103, which
digs into the subject of turbine lubrication.

America’s
Most Powerful High-Speed Gears

HE De Laval double-helical speed-reducing gears shown herewith are the

most powerful ever built in this country tor high-speed turbine service.

They are driven by compound turbines and transmit 22,500 hp. at a propeller
speed of 360 r. p. m. ;

Such gears have been made possible and successful only by the De Laval
policy of liberal design and precision in manufacture, combined with 25 years
of turbine and gear experience.

Over 2,000,000 H. P. of De Laval marine gears are now in service. Many
of them have traveled over 200,000 miles each, and all are giving perfect
satisfaction. De Laval gears are unique in this respect.

De Laval reduction gears are exceedingly quiet in operation and are
highly efficient, as demonstrated by their record in service. Noisy reduction
gears greatly reduce the efficiency and morale of engine room crews, who
depend upon their hearing more than upon any other sense to locate trouble.

A series of two or more Winton Oil Engines, each connected to a Westinghouse
Generator, generating power and supplying it to a driving motor located in the
stern, makes an ideal installation for many different types of ships. The power
plant can be placed advantageously, it occupies less room than any other type of

Weight—A Large Factor in Ship Operation

Marine boiler weights are now receiving serious con-
sideration, especially in passenger or freight ships re-
quiring large power. Formerly the excessive weight of
Scotch boilers was thought necessary to assure reliable
operation. The modern demand for fuel economy, how-
ever, requires higher steam pressures and temperatures,
with lower boiler weights. This caused the introduc-
tion of water-tube boilers in naval vessels. Practically
all naval boilers are now of the water tube type and the
merchant marine is rapidly following successful naval
practice. .

Even in moderate-powered cargo ships the weight of
boilers is a large factor in ship operation. A typical
cargo ship of 10,000 tons and 3,000 S.H.P. requires three
boilers. With Scotch boilers and their necessary auxil-

iary equipment, such as forced draft fans, air heater
and auxiliary foundations, the boiler weights will be
approximately 300 tons. Similar sized water-tube boil-
ers complete will weigh 165 tons, a net saving of 135
tons cargo carrying capacity. The increased weight of
fuel necessary with Scotch boilers is also a considerable
factor on long voyages.

Foster Marine Boilers are designed with careful con-
sideration to weights of pressure parts, casing insula-

‘tion and water storage necessary for steady steaming.

The weights of all steel parts are amply heavy to last
the life of the ship without reduction in pressure due to
Wear.

The Foster boiler weights are carefully analyzed in
our catalogue.

Ked-Lead means years to a ship

Dutch Boy Red-Lead

MARINE ENGINEERING
AND SHIPPING AGE

Experience proves that two
or three coats of red-lead,
applied to the hull on the
ways, with ample time to dry,
will add years to the life of a
ship, and aid in maintaining
speed by keeping the bottom
free from pitting.

Dutch Boy Red-Lead pro-
tects metal. It provides a
tough, elastic, moisture-proof
coat that sticks tight and pre-
vents rust. It won't flake or
scale off, if applied to clean
metal surfaces, and it gives an
unequaled foundation for fin-
ishing coats.

The U.S. Navy uses a great
deal of red-lead, with stiff
specifications for purity —-

specifications that Dutch Boy
Red-Lead meets.

Its convenient paste form,
its fineness and purity, its re-
markable spreading power,
and its long life make Dutch
Boy Red-Lead the most eco-
nomical paint for metal sur-
faces.

For every metal surface on
shipboard, use Dutch Boy
Red-Lead—for first coats at
least, Ile Cain los. iinwecl to
black, brown, and green for
finishing coats; if white or
gray is desired, use Dutch
Boy White-Lead.

SOOT REMOVAL FROM SCOTCH

MARINE BOILERS

is effectively accomplished by the improved Diamond Rear End Blower
(Model B).

And soot removal is essential to economy. Power is one of the largest
items of expense in the cost of operating a vessel, and the cost of fuel
represents on the average 70 per cent. of the cost of power. The pres-
ence of soot has cost—it still costs—a loss of hundreds of thousands of
tons of coal and hundreds of thusands of barrels of fuel oil a year to ship ‘ Nes SO
owners. Soot waste has been eliminated on many ships, and it can be S

eliminated on all with a consequent notable increase in boiler efficiency
and a consequent great increase in marine profits.

Method of installing Model B blowers
Thousands of Diamond Model B Blowers are in use today on Scotch on a three-furnace Scotch boiler.
Marine boiler. The blower is permanently installed through the rear

water leg, a hole being cut in the plates and a section of tubing expanded

and beaded into place. The blower is encased in this tubing. When not

in use the blower is secreted in the casing. As the steam is turned on

the nozzle is automatically forced forward into blowing position. In

operation dry steam is shot into each tube with the draft at a terrific

velocity, sweeping and scouring the soot from the full length of the tubes.

Diamond Soot Blowers save fuel and labor. Write for full information on blowers for
any type of boiler, requesting your copy of Bulletin 134, ‘“How Some Ship Owners Have
Increased Their Profits.”

For the charcoal iron tube, the manufacture of which dates
back a century, superior resistance to corrosion and _ pitting
and greater dependability are claimed and established.

60 SECONDS Make This Test.
i y}on YOUR Pipe and
=== = // Boiler Covering |

The saving effected by a pipe and boiler covering
depends on a number of qualities—strength, light-
ness, ability to stand heat without injury, number
and character of tiny air spaces, etc. If the voids
holding dead air are too continuous—spongelike in
character—heat will penetrate the covering quickly
A, SEC like water and escape.

3 The above drawing pictures a test made frequently
and one that you can make for yourself. Four cubic-
inch pieces of well known pipe covering were thrown

into a bowl of water. The 85% Magnesia cube, as will be seen, floats considerably longer than the others—
60 seconds. The air spaces of 85% Magnesia are more numerous and much less continuous than those of any
other known insulating material. This accounts for its remarkable insulating quality.

Witt

ddd

85% Magnesia Pipe and Boiler Covering could be made both heavier and stronger, if that were desirable. But it
is made just heavy and strong enough for all practical purposes and this permits full insulating quality.
~)

With the present price of coal, you should put your pipe and boiler covering to the severest practical tests. Ask
us for further data on heat insulation, sent free of obligation. This Association, as such, has nothing for sale.

Briggs Composition is an invaluable rust-pre-

It is particularly effective in double bottoms,

Marine Paint

Actually Pays You For Using It

—because, in the final reckoning, your
painting costs will be lower with Federal
than with other marine paints.

The heaviest items in the cost of painting
your ships are dock-charges and labor—
these are the same, whether you use Fed-
eral or some less durable protection. But
a coat of Federal adheres so closely, and
has such toughness and wear-resisting quali-
ties, that painting is needed much less often.

Federal Paints and Compositions are to be
had in a full range of colors, for all classes
of vessels, and for every marine purpose.
Our products include Bottom Compositions,
Boottopping Compositions, Topside Paints,
Hold Enamels, Deck Paints, Deck House
Paints, Mast and Bulwark Paints.

You can have any quantity for quick deliv-

You use large turnbuckles for temporary

fastenings in the construction of ships and
when making repairs. Each time a turn=
buckle is used the workman must find a
wrench or bar with which to turn the buckle.
How much time does that workman lose
while hunting that wrench or bar?

When the turnbuckle must be loosened the
same proceedure must be used. More time lost.

Bradley

Hammer
Motor
Drive

The Bradley Hammer has been found practically in-
dispensable for forging liners in shipyards. Accurate
and rapid, these hammers attain big results in many kinds
of forgings. They are built to stand the strain of con-
tinuous work.

Pressure on the foot treadle starts the hammer by
bringing the idler pulley against the drive belt. When
the treadle is released a brake stops the hammer. .

Both the speed and force of the blow are thus com-
pletely under control of the operator.

“Solved Sconomically

Don’t figure on how little you can buy a valve for but
how much you spend a year on valve repairs and re-
newals. That is the only way to give yourself a square
deal in computing valve costs.

Computed on the basis of cost-per-year, there is no
valve as economical as a

Pratt & Cady Renewable
Valve

Scientifically designed to resist wear at the points of
greatest stress, and fashioned with the utmost skill
from metals of proven strength and reliability, they are
a synonym for “durability.”

When a P. and C. Renewable becomes worn, a new
seat ring can be easily inserted in the Gate type valve,
or a new disc in the Globe type, without removing the
valve from the line. The valve then becomes virtually
a new valve at about 10% of what a new valve would

cost.

BLOODED-STOCK |

If you were buying a horse and he was
just a horse you would have to take for
granted the things the owner said, and
then wait for experience to show if he
had spoken the truth.

But if you bought a horse of blooded
stock that had a pedigree, you would not
need to take the man’s word for it. The
pedigree would show his ancestry and
race and give you an idea of the animal’s
capacity for speed and endurance.

It’s the same in buying advertising
space. Some publications sell “just a
horse” and you have to take their cir-
culation statement with a pinch of salt.

MARINE ENGINEERING is blooded
stock. An A. B. C. statement is the
pedigree that tells you what to expect in
the way of speed and endurance.

\VESINS Marine Engine Oil — for
thrust bearing and reciprocating en-
gine lubrication—is the latest develop-
ment among the Sun Marine Oils. It
conforms in efficiency with the high stand-
ards maintained for years in the famous

Sun XX Marine Oil.

Viking Engine Oil, by reason of a
special patented refining process, will form
a perfect and lasting emulsion with either
salt or fresh water.

The body of this emulsion may be
varied from a heavy pastelike substance
to any consistency by the simple addition
of a larger percentage of water.

For lubrication of thrust bearings an
emulsion of Viking Oil with from 50 to
75 per cent water is recommended.

When used for main bearings without
the addition of water, Viking Oil has
high viscosity and extremely low internal
frictional values. It will absorb any
water that may find its way into the bear-
ings and will feed indefinitely through a
wick without clogging the pores.

Although having the saponifiable value

Viking Marine Engine Oil

of oils highly compounded with blown
rape seed, Viking Marine Engine Oil
will not deteriorate and become rancid
with age.

In addition, Viking Oil is neutral in
reaction and contains no fatty acids, thus
eliminating the corrosion of metal parts
produced by the high acid content of
most marine oils. It is unaffected by low
temperatures.

The Sun Company is one of the
world’s largest producers, refiners and
shippers of petroleum products. Its out-
put of lubricating oils alone exceeds a
million and a half gallons per week.

The Sun Company has specialized for
a quarter century in lubricating oils. It
has developed into an organization of
lubrication experts, its aim being to sup-
ply accurate and efficient lubrication in-
stead of just “oil.”

The choice of a lubricant for any par-
ticular purpose demands expert advice.
Engineers of the Sun Company are avail-
able to make an analysis of your lubrica-
tion requirements and specify the right
oils to meet them. ‘This service is free.

Life-savin

“Safety at Sea”

MARINE ENGINEERING
AND SHIPPING AGE

Life Saving Efficiency

At the 1921 spring meeting of the Institute of
Naval Architects, Mr. Peskett, Naval Architect of
the Cunard Line, very aptly said:

“Ships today are not built for the cost paid in
pre-war days, and although safety must come
before all other questions, the prevailing pres-
sure ut economic conditions seems to present a
most opportune moment to develop what are
most essential in life-saving appliances and to
dispense with all that are likely to be imprac-
ticable.”

The entire resources of the Steward Davit & Equip-
ment Corporation are devoted to the saving of life
-at sea. Fully complying with the legal require-
ments in this country and abroad, it is our desire to
provide life-saving equipment that may justly be
classed as the most efficient and trustworthy in the
world.

It has been our privilege to have a very broad
experience, measured in ships served, in this par-
ticular field. Steward Life-Saving Equipment is now
installed on a large number of vessels of the U. S.
Navy, the U. S. Army Transport Service and in com-
mercial lines; on cargo vessels, tankers and on many
of the finest passenger ships afloat.

Steward Life-Saving Service

At your request we will send an engineer to your
ship to make a detailed and strictly confidential
report of the condition of your life-saving equip-
ment. You will have the positive assurance that the
laws have been complied with in proper form for
your legal department and in the event of future
need a dated and affirmed record will be on file for
your protection. There is no charge for this service
in New York waters.

True economy is not how
little you pay for an article but
how much value you get out
Or mt, AY “barcamm’ iim cane
lessly manufactured and im-
properly seasoned lumber
means an unsatisfactory struc-
ture from the first and expen-
sive repairs soon or late.

There can be no compro-
mise with poor lumber and

timbers in ship, barge and
dock building. The demands
for uniform strength and dur-
ability are too exacting for
“savings” of that kind. South-
ern Pine products bearing the
Long-Bell trade-mark come to
the user only after being sub-
jected to vigilant inspection
from tree to loading dock,
thereby assuring uniform high
quality.

Oil Engines

Price Oil Engines are flexible. The average
time for reversing from full speed ahead to full
speed astern is only seven seconds. The en-
gine control and reversing are accomplished by
a single lever, there being no shifting of cams,
camshafts or gears.

These oil engines operate on the four stroke
cycle. Ignition is by temperature of compres-
sion only. The fuel atomization is direct and
positive without the use of compressed air.

Price Marine Oil Engines are built in sizes
ranging from 150 to 750 H.P.

THE CHAMPION RIVET COMPANY

CLEVELAND, O.

Recently one of the largest consumers
of Rivets in this country made inquiry of us for
price on their contract requirements. Our quo-
tation did not secure the business. |

A few days later, we received an inquiry
from these same people for a car load of rivets.
We quoted exactly the same price we named on the
contract and secured the order.

Our representative was anxious to know
why our price on the car load secured the order,
but failed to secure the contract.

The Purchasing Agent said, ‘‘Well, the
job for which we wanted the car load being a
very particular one, our Shop Superintendent
insisted on getting VICTOR RIVETS made by The

Champion Rivet Company''.

Respectfully submitted,

It can’t be overworked

A Shepard Electric Traveling
Crane is built for severe service
—and faultlessly responds. It is
capable of handling a capacity
load (or reasonably over) every
working hour, every day, year in
and year out.

Because operating mechanisms,
both electrical and mechanical,
work within tight metal housings,
the elements, dirt, dust, or damp-
ness, can in no way impede the
efficiency of a Shepard Traveling
Crane. Gears operate in baths
of oil, assuring thorough, even
lubrication.

All running parts of the crane
trolley are maintained in correct
alignment, keeping the pressure
and stresses in gear teeth, bear-
ings, brakes, etc., within safe
limits.

Shepard Engineers are at your
service. Call upon them.

Doctoring a deck

OZENS of time and labor saving applications have made the
process of gas welding and cutting indispensable in ship yards.

Because of its uniformly high purity, exceptional portability and

constant availability

DISSOLVED ACETYLENE
has proven the most satisfactory gas for welding and cutting in ship

building and repairing.
Forty plants and warehouses insure immediate deliveries of Prest-

O-Lite anywhere and in any desired quantity —a never failing service
that has greatly enhanced the value of Prest-O-Lite in the hundreds of

yards where it is regularly used.

EW people realize the enormous

work done by Linde in keeping

the wheels turning on our railroads.

The recent National transportation

tangle would have been a thousand times

worse but for the quick and permanent

repairs on rolling stock and rails made
possible by the oxy-acetylene process.

Linde Oxygen, because of constantly

uniform purity and unfailing deliveries,

Behind the locomotive—Linde

is used for this highly important work
by almost all railroads of standing.

Whenever time is a weighty factor in
repair work Linde Oxygen and Linde Ser-

From Pontoon to Superdreadnought
During the twenty-odd years of its existence
the New York Shipbuilding Corporation has not
only turned out many repetitions and variations
of the same type of vessel, but has built vessels

of almost every known marine type—literally
from “pontoon to superdreadnought.”

From the accomplishments of the past it is
able to bring to new ship construction a wealth
of experience gained in both quantity production
and specialized output. The New York Ship
yard is a specialist not merely in one type of ves-
sel but in many—it might be said in all.

Passenger liners, tankers, colliers, general
cargo carriers, destroyers, battleships, cruisers,
mine-planters; carfloats, ferryboats, tugboats,
dredges; each type, each different size or class,
reflects the diversified skill, the completeness of
shop and yard facilities of this great shipyard.

The Same Economy
After 5. Years’
Service

Due to the
principles upon
which Terry
Turbines oper-
ate.

No. 2—Photo-
graph of a new
Terry Wheel
for compari-
son.

No. 1—Photo-
graph of a
Terry Wheel
which has
seen 5 years’
service.

Both of these
wheels will operate
with the same efl-
ciency in spite of the
fact that the one on
the left has seen five
years of continuous ser-
vice. The arrows indicate
the direction in which the
steam flows with respect to
the wheel. The power pro-
ducing action takes place on
the curved surface at the back of
the bucket which we have revealed
by removing a portion of the blade.

Wear on this surface, because of the
complete reversal, does not alter the
entrance or exit angle of the steam. ‘Therefore, the action of the
steam will remain the same as when the turbine was new, which
means that the efficiency will like-wise remain unaltered.

How

FOSTER SUPERHEATERS

affect marine
boiler economy

Marine boilers are generally designed to operate
at a capacity of from 5 to 6 Ib. evaporation per sq. ft.
of heating surface. gee

This capacity usually results in stack temperature
of 600 to 650° with Scotch type boilers and 500 to
550° with water tube type boilers. With Scotch type
boilers, Foster Marine Waste Heat type superheaters |
will reduce the stack temperature over 100°. For this —
reduction in temperature a superheat of from 50 to
60° F. will be produced and the-boiler economy in-
creased from 3 to 4%.

The 50 to 60° superheat will reduce the steam
consumption of the main engine approximately 8%

Foster Marine Superheaters installed in uptake of or the steam consumption of the main turbine about
Scotch Marine Boiler 6%. There is, therefore, a saving in fuel due to the
reduction of gas temperature and a further saving in

fuel due to the reduced steam consumption.

In water tube boilers the Foster superheaters are
usually installed in the nest of tubes at a point where
the temperature is sufficient to maintain the superheat
desired. This superheating surface usually reduces
the stack temperature about 50°. The superheat
gives the same reduced steam consumption in the
propelling equipment as the Scotch type Foster super-
heater.

The fuel economy obtained with Foster Marine
superheaters can be maintained steadily by using the
soot blowers at least once each day. If the boilers
do not prime excessively there will be practically no
cost of repairs.

THE CAPTAIN KNOWS

“Men who go down to the sea in
ships’ have, since 1824, been using a
rope, light, strong, flexible and almost
wear- proof, that is made in Plymouth.

Made in the early days to exactly
meet the needs of the times, Plymouth
Rope today possesses just a little more
wear, a little more strength, a little
more flexibility than do other ropes.

That is why the ship captains of to-
day, like the captains of those famous.
ships of the first American Merchant
Marine, prefer that their ships be
equipped with Plymouth.

You too will find, as have these
experts, that Plymouth is The
Rope You Can Trust.

5 ~ Step Clearance Control
tee a 2 mia Ole Ou Ge kes compressors

Graduated capacity control on belt driven air compressors.

The introduction of the XCB Air Compressor presents for the first time an efficient and graduated
capacity regulation for belt driven air compressors.

TheI-R 5-Step Clearance Control is admittedly the most efficient and simple air compressor regulation.
For years it has been standard on our large direct connected electric driven compressors. Now it
can be furnished on belt driven units as small as 100 H. P.

The unloading is entirely automatic.

The demand for air is seldom steady throughout the day. With the 5-Step Clearance Control the
Compressor automatically operates at full, three-quarter, one-half, one-quarter, or no load as required to
maintain the desired air pressure.

Guarantees efficient operation at partial loads.

The reduction in power secured with this method of control is practically in direct proportion
to the quantity of air produced.

This new type of compressor is known as the “Imperial” Type XCB. These units are é ee
fitted with Ingersoll-Rand Plate Air Valves, and may be furnished with or without Cee
short belt drive and electric motor. bs ad

Spellerizing

NATIONAL PIPE —

HEN PIPE METAL IS UNIFORM THROUGHOUT
there is less tendency to corrode, or to deteriorate
through other causes; therefore, the metal for “NATIONAL”’

Pipe is made by processes which give the utmost uniformity.

Spellerizing (mechanical roll-knobbling) is one of the
special processes employed to give a uniformly dense,
fine-grained surface texture to all “NATIONAL” Pipe,
sizes 4-inch and under, and thereby reduce any tendency
to galvanic action (corrosion). This feature makes
“NATIONAL” Pipe especially desirable for Marine Service,
where conditions affecting piping are particularly severe in

What one of the World’s Largest
Air Drill Users just found out

NENE months ago one of
the largest pneumatic
tool users in the world —a
prominent ship - builder —
decided to satisfy itself con-
cerning the relative economy
and operating advantages
of various makes of portable
air drills.

‘Three makes of air drills in-
cluding the Little Giant were
selected for this test. All
drills were operated under
identical service conditions for
nine months.

Tests to determine horse-
power, drilling speeds and
air economy were made at

the end of the nine months. |

These tests, plus accurate
records kept during the
period, proved the follow-
ing:

That Little Giant Air Drills
were the most economical be-
cause they

— consumed less air per foot-
pound of work done.

—had better speed charac-
teristics.

—had greater spindle forque
from speed-light to stal-
ling point.

—or in other words developed
greater horse-power under
every condition of load.

Let a C-P Service Engineer
prove the above statement.
Or, better yet, make the
same test in your own plant
with one or a number of
Little Giants applied to the
definite work which such
tools perform, under your
own requirements.

Little Giants are built in a
complete line for every dril-
ling, reaming, tapping, screw-
setting, nut-and-bolt tighten-
ing or other shop require-
ments. Address the nearest

vice. Also ask for Bulletin

Special machinery insures accurate pitch

Then thorough inspection practically

oil and protects machinery on the Hawkeye State

De Laval Oil Purifiers save oil by making
it unnecessary to ever pump a drop of it over-
board. Once through the De Laval, the dirti-
est oil is completely purified and is ready for
another period of use—free from water, dirt
and particles of metal. Emulsions readily
yield to De Laval centrifugal purification so
that this worst enemy to efficient lubrication
is eliminated.

De Laval Oil Purifiers protect machinery,
because they make it easier and cheaper to

use clean oil than to use that which has be-
come foul through use. Bearing trouble is
reduced to the minimum; gears run smoother
and last longer. And on the Diesel-driven ship
corresponding savings can be made by centrif-
ugally purifying crank case oil.

Bulletins Nos. 102 and 103 describe the De
Laval Oil Purifier in detail and tell how you
can get better lubrication at less cost. Write

You Can Get More Speed From

The Same Boilers With Less Fuel By
Installing De Laval Geared Turbines

IVE 10,500-ton tankers were recently refitted with De Laval Compound turbines and double-

reduction gears. The substitution of De Laval geared turbines for the original equipment
made it possible to raise the speed materially without any increase in boiler or condenser ca-
pacity. Compared with similar vessels driven by reciprocating engines, approximately a knot
and a half greater speed is obtained from 10 per cent less total steam.

De Laval turbines are of the impulse type, with large clearances, and can be quickly
reversed, permitting rapid and easy maneuvering. An interlocking gear prevents admission
of steam to both ahead and astern tur-
bines at the same time.

Over 2,000,000 hp. of De Laval gears
are giving satisfactory service. De
Laval gears are practically noiseless in

- operation, which is not only an indica-
tion of perfect cutting, high efficiency
and long life, but also is necessary for
proper attention, since trouble in ma-
chinery is most often detected by

Three P & H Cranes conveying monster engine bed casting after being raised from mould.

LIFTING A 225-TON LOAD

At a signal from the floor man, the crane operators moved their controllers,—crane slings
and hoisting cables tightened. Then from the dark depths of the cavernous mould, shaken
from the grip that held it, came the huge casting of an engine bed.

Monster weight that it was, the three P & H Cranes raised it gently aloft, working
smoothly and precisely. The gentle hum of the electric motors, the quiet running of the cut
tooth steel gears, the free travel along the runway, gave little hint of the bigness of the job

LIFE—A LARGE COST FACTOR

With Scotch marine boilers it has been cus-
tomary to consider re-boilering necessary at least

once during the ship’s useful life and in some
cases oftener.

The cost of the first set of water-tube boilers
is usually the final cost. This cost is not only
less than the first cost of Scotch boilers, but it
saves the expense of laying up a ship for a long
period during its useful life to renew boilers as
well as the cost of the new Scotch Boilers.

The life of marine boilers is dependent on de-
sign and operation. The design of Scotch boil-

ers is a fundamental cause of short life as its lack
of circulation produces strains which promote
leakage and result in constant caulking, finally
making new boilers necessary. The design of
most water-tube boilers insures rapid circulation,
even temperature of all parts of the boiler and no
wear of essential parts due to caulking, tube roll-
ing, etc., therefore, their useful life is in many
cases longer than the ship.

Foster Marine Boilers are correctly designed
for a long life with minimum repair costs.

The Foster Catalogue shows why this boiler
has a long life.

The World’s First Diesel-Electric Cargo Ship

HE reliability and efficiency of Diesel engine-electric
drive will soon be further demonstrated on the 2,200
dead weight ton ‘‘Fordonian’”’ to be the world’s first
Diesel-electric cargo ship, now having its Diesel-direct
drive replaced by Diesel-electric drive at the Tebo Yacht
Basin of the Todd Shipyards Corporation.

The General Electric Company with its many years ex-
perience in the marine field was the first to successfully
apply Diesel-electric propulsion to ships. The electric
equipment for the 150-foot fishing trawler ‘‘Mariner’’
was furnished by this Company and has been in service
since February, 1920.

Diesel engine-electric drive with G-E electric equipment
was chosen for the ‘‘Fordonian”’ because of its highoverall
economy, saving in hull space, ease and flexibility of
control, and reliability.

The General Electric Company supplies generating and
control apparatus, propulsion motors, and motors for
engine room and deck auxiliaries of every kind for Diesel-
electric ships.

It costs a great deal less to put
on a coat of Dutch Boy Red-Lead
than to build a new ship. In fact,
the cost of painting would be ab-

sorbed in a. few days extra life of

the ship.

Every vessel should have two
or three good coats of red-lead
while she is building, with plenty
of time allowed for drying. This
is particularly important for. un-
derwater parts.

Special topcoats may be neces-
sary for special purposes, as in
water and ballast tanks, but the
priming coat should always be red-
lead.

In the Navy “red-lead is the pro-
tective paint commonly used on
metal surfaces” (to quote from

Hull still in good con-
dition .after two years at
the bottom of Lake Erie.
Painted with Dutch Boy
Red-Lead.

Red-lead is cheaper than ship’s plates

The Bluejacket’s Manual) because
it gives the best protection against
the destructive action of salt water.

Dutch Boy Red-Lead meets
Navy specifications for purity—
freedom from litharge. It doesn’t
harden in the pail. No red-lead is
wasted; no time lost by the
painter.

Dutch Boy Red-Lead has the
added advantage of greater spread-
ing power than other paints for
marine use. It covers the steel
with a tough, elastic, uniform coat
that won’t peel or scale.

And soot removal is essential to economy. Power is one of the largest
items of expense in the cost of operating a vessel, and the cost of fuel
represents on the average 70 per cent. of the cost of power. The pres-
ence of soot has cost—it still costs—a loss of hundreds of thousands of
tons of coal and hundreds of thusands of barrels of fuel oil a year to ship
owners. Soot waste has been eliminated on many ships, and it can be
eliminated on all with a consequent notable increase in boiler efficiency
and a consequent great increase in marine profits.

and beaded into place. The blower is encased in this tubing. When not

in use the blower is secreted in the casing. As the steam is turned on

the nozzle is automatically forced forward into blowing position. In

operation dry steam is shot into each tube with the draft at a terrific

velocity, sweeping and scouring the soot from the full length of the tubes.

The heating of fuel oil before discharging
it through oil burners is a necessary opera-
tion, consequently your oil heater is a very
important part of your oil burning system.
Oil is a poor conductor of heat, and in
order to heat it efficiently and quickly it
should be caused to flow over the heating
surfaces in a film-like condition and at a
high velocity in order to obtain maximum
heat transfer.

SPIRAL OIL FILM

On account of the thick and viscous crude
oils and residuum which are employed to-
day for fuel purposes, this maximum heat
transfer will not maintain unless the heat-
ing surfaces of your heater can be kept
clean. Would you have a boiler in your
plant whose heating surfaces could not be
cleaned?

In turbine installations requiring forced feed lubrication of bearings, better results are obtained at high oil
velocities, as it is of advantage to circulate a large quantity of oil through a small range of temperature, thereby
keeping the oil moderately near the bearing temperature for the reason that warm oil absorbs heat more
readily than cold oil.

Ship Radio Inspection
One Phase of World-Wide Wireless

The interest of the Radio Corporation of
America in its ship-sets does not end with their
installation. Inspection Service Stations are
located in all important seaports. Through
these stations the Radio Corporation of
America keeps its ship-sets at the highest point
of efficiency.

Ship-sets may be bought or leased from the
Radio Corporation of America. But whether
bought or leased the ship owner commands the
Radio Corporation of America’s Inspection
and Maintenance Service. Ship owners may

also call upon the Radio Corporation of
America for licensed, highly skilled operators.

All this is but part of the World-Wide Wire-
less service of the Radio Corporation of America
at all important seaports of the United States.

The Radio Corporation of America has equipped
thousands of ships with wireless apparatus. This appa-
ratus always embodies the highest engineering skill. For
behind the Radio Corporation of America stand the
splendidly equipped Research Laboratories of the Gen-
eral Electric Company, the American ‘i elephone & Tele-
graph Company, and the Western Electric Company,
where, year in and year out, eminent physicists conduct
investigations that result in new radio advances.

An Indication of Confidence

As a general thing, ships equipped with charcoal iron boiler
tubes carry only a few extra tubes for emergencies, while
ships fitted with tubes of other material usually carry a full
set of spare tubes.

The confidence thus evidenced in the charcoal iron boiler
tube is the natural result of years of dependable tube service.
Charcoal iron tubes are practically standard in marine use.

Specify Parkesburg Charcoal Iron Boiler Tubes. They are
made of genuine charcoal iron, are easily applied, and give
years of service.

Shove a thin rule

up through a joint yp
your pipe cover ing

If your test shows that the distance from the pipe to the outside
of the covering is the thickness of the covering, then there is no loss
through sagging.

But often such a test shows that, though the covering looks snug
from the outside, it has charred and sagged perhaps a quarter of an
inch and air currents are moving along under the pipes and escaping
at the joints. Such a pipe covering is robbing you daily.

Some pipe coverings contain from 20 to 22 per cent. of inflam-
mable material that chars under high temperature and gradually
develops a sag.

85% Magnesia, on the other hand, is not affected adversely by very
high temperatures. Tests at temperatures continued at from 700 to 900
degrees show an actual gain of about three per cent. in
efficiency. No other material has the heat-saving
efficiency of 85% Magnesia. It is light and yet strong
enough. Neither water nor heat impairs it.

Ask for a copy of our revised book, “Defend Your
Steam,” giving much valuable information about
heat insulation, tables, interesting applications, etc.

16,000 Miles Through

From Seattle to Nome, Alaska,
and thence to the Siberian Coast—
16,000 miles in all—is the record
made by the “Bender Brothers” on
her first trip with her new 100
H.P. “C-O” engine.

Her skipper says that even in
the heaviest weather in the ice
bound Arctic, her engine performed
steadily and drove the schooner at
an average speed of seven and
one-half knots.

“C-O” oil engines, 30 H.P. to
300 H.P., using low priced fuel oils,
have established records for un-
usual fuel and operating economy
on all classes of work craft in all
waters.

They are simple and sturdy in
construction, without carburetors,
igniters, timers, switches, or mag-
netos. Easy to start and operate—
inexpensive to maintain.

housands of Fuses

What would happen if the boiler of a railway
locomotive were made of fibre the thickness of
that used in fuse casings?

That is just what happens to fuses that are not
constructed to let the pressure of gases escape
quickly when there is a blowout. For blowouts,
especially if caused by short circuits, frequently
create a pressure higher than that carried by
locomotives.

We have at last discovered a way to let the pres-
sure blowout escape before it has time to do any
damage to

“Union” Renewable Fuses are now
built with four safety valves on each
end.

These safety valves consist of small
vents or holes in the metal washers,
but without a hole in the leather
washers. So you see, when a link
blows, the pressure lifts the leather
washers enough for gases to escape,
yet not sufficient to permit any flame
to pass. ’ : : i men
Simple, isn’t it? So simple it’s a wonder MH

no one ever thought of it before. Yet, it |
will save thousands of fuses from being
blown to atoms.

“Union” Fuses have many other valuable features
found in no others—features that make them the
cheapest fuse on the market to use.

[The‘<Union’’saves more than ANY other renewable fuse. |

“Union” Fuses, both Renéwable and~ Non-Renewable, are
for sale by all leading jobbers and dealers.

BROWNHOIST

Makes Freight Handling Easy

This big Brownhoist Portal Pier type Loco-
motive Crane will toy with most bulk and pack-
age cargoes which sometimes cause so much
trouble in unloading. With its long, high boom
it will reach any point on the ship, doing its
work rapidly and with no confusion. Or with
the auxiliary hoist, it has the titanic strength
to lift packages weighing tons and to place
them wherever you may choose.

HOW TO TELL
GOOD WRENCH—
LOOK FOR THE

To the casual user, perhaps, all
wrenches may /ook much alike,
yet an apparently slight variation
in design, or material, or process
of manufacture may mean all the
difference between good wrenches
and poor.

We have been making Superior
Drop-Forged Wrenches for near-
ly half a century and every feature
that experience has taught us is
valuable, is embodied in these
tools.

We've a wrench for every purpose
—40 standard patterns in 1000

sizes, with openings from 3/16 to
75% inches.

“CORONA”’—a converted Sub-Chaser, 110 feet long, owned by

O MATTER whether it be a Tug

Boat, a Fishing Boat,a Motorship,
or just a plain, everyday “work boat,”
consistency, speed and efficiency is
what makes the difference between
profit and loss.

The propeller is a mighty important
point, more losses are probably caused
by poorly designed and easily broken
propellers than any other one cause.

Which possibly explains why an in-
creasingly large number of work boats
of all sizes and types are replacing their
cast iron wheels with Columbian
Bronze Propellers.

Motor
Drive

The Bradley Hammer has been found practically in-

dispensable for forging liners in shipyards. Accurate
and rapid, these hammers attain big results in many kinds
of forgings. They are built to stand the strain of con-
tinuous work.

Pressure on the foot treadle starts the hammer by
bringing the idler pulley against the drive belt. When
the treadle is released a brake stops the hammer.

Both the speed and force of the blow are thus com-
pletely under control of the operator.

Viking Marine Engine Oil

WS Marine Engine Oil — for
thrust bearing and reciprocating en-
gine lubrication—is the latest develop-
ment among the Sun Marine Oils. It
conforms in efficiency with the high stand-
ards maintained for years in the famous

Sun XX Marine Oil.

Viking Engine Oil, by reason of a
special patented refining process, will form
a perfect and lasting emulsion with either
salt or fresh water.

The body of this emulsion may be
varied from a heavy pastelike substance
to any consistency by the simple addition
of a larger percentage of water.

For lubrication of thrust bearings an
emulsion of Viking Oil with from 50 to
75 per cent water is recommended.

When used for main bearings without
the addition of water, Viking Oil has
high viscosity and extremely low internal
frictional’ values. It will absorb any
water that may find its way into the bear-
ings and will feed indefinitely through a
wick without clogging the pores.

Although having the saponifiable value

of oils highly compounded with blown
rape seed, Viking Marine Engine Oil
will not deteriorate and become rancid
with age.

The Sun Company is one of the
world’s largest producers, refiners and
shippers of petroleum products. Its out-
put of lubricating oils alone exceeds a
million and a half gallons per week.

The Sun Company has specialized for

-a quarter century in lubricating oils. It

has developed into an organization of
lubrication experts, its aim being to sup-
ply accurate and efficient lubrication in-
stead of just “oil.”

ANCHOR
CHAIN CABLE

IS THE ONLY CHAIN MADE WITH LINK AND
STUD ONE SOLID PIECE.

It is greater in strength, more uniform in size and shape,
and easier of operation than any other type of anchor
chain cable. ~

The studs in “Naco” links being cast of the same metal
and integral with the link (not inserted afterward), can
never be lost or even loosened. THIS IS the greatest
sateguard against kinking, and an assurance of smooth
operation in service.

What Balsa Insulation Means to the
Shipowner and Shipbuilder

ALSA insulation, economical in main-
tenance of refrigerated.ship spaces and
practical in the simplicity of its instal-

lation, provides the solution for the many
difficulties heretofore encountered in con-
struction and upkeep. By the use of Balsa
full insulating values are maintained, with-

out replacement, year after year;
there is a saving of as much as
fifty percent of the weight of the
insulating structure; thinner
walls increase the available cargo
space; and the original cost of the
completed structure is less than

In the last eighteen months more than
a million board feet of Balsa insulation have
been installed following the thorough devel-
opment of its use during the last ten years.
Methods of treatment that retain the high
insulating value of this lightest of all woods,
have been fully proven. Standard plans of in-
stallation have been established.
Balsa has met successfully all
those tests and conditions to
which an extended period of
actual use has subjected it. Its
use has brought about a new
appreciation of the possibilities

with other good materials.

of economical ship insulation.

END WINNICANGIES QU8 Ie Syey SleQUP UNSW ILA ION

Balsa is supplied in large panels having a structural strength
fully half that of spruce.

Baisa requires little studding and only a single layer of sheath-
ing for surface protection.

Its resistance to heat transmission is equal to that of other
high grade insulating materials.

Balsa is even lighter than cork, and the weight of a completed
installation is fully 50% less.

Permanence of structure and of insulating efficiency is obtained
through exclusion of moisture.

Balsa panels are easily installed, a small number of tight fit-
ting joints minimizing heat leakage.

Removable sections can be installed to permit ready inspection
of ship’s hull for painting or repairs.

Metal sheathed Balsa panels are available for insulation of
boiler room hatches and crew quarters.

An article which appeared in the July, 1921, issue of International Marine Engineering, describing

Balsa ship insulation, and including detailed drawings showing standard plans of installation,
has been reprinied for distribution to those interested. May we send you a copy of this article?

A few days later, we received an inquiry

We quoted exactly the same price we named on the
contract and secured the order.

Our representative was anxious to know
why our price on the car load secured the order,
but failed to secure the contract.

Impervious to weather

A Shepard Electric Traveling
Crane, in all of its working parts,
both electrical and mechanical, is
“element proof’—rain and damp-
ness, or sleet and snow cannot
“touch” vital parts. Tight metal
housings form an impenetrable
protection. Mill dirt, dust, and
fumes are likewise effectively
kept out.

You buy permanence (steady,
consistent operation) when you
invest in a Shepard Crane. It is
a crane that functions properly
and dependably as often as called
into service.

Thorough, even lubrication of
Shepard Cranes is provided by
oil baths in which gears operate.
All running parts of the crane
trolley are maintained in correct

and stresses in gear teeth, bear-

“Shepard” builds Electric Trav-

Monorail Transfer Cranes; Elec-
tric Winches; and Electric Cargo

The necessity of the day is reduced
overhead.

A reduction in engine room costs
is the opportunity open to place
American Shipping on a sound
basis.

Fuel costs, one of the largest items
of ship overhead, can be reduced 10
to 15% through superheating.

The success of Fire Tube High
Degree Superheaters is proved by
years of service on 2500 ships oper-
ating all over the world.

DISSOLVED ACETYLENE

provides ship builders with the purest cutting and welding

gas in easily portable, instantly accessible and highly conven-
ient cylinders.

Without such a supply of uniformly high grade gas always
at hand, cutters and welders would find impossible many

applications of the oxy-acetylene process now in common use.

And Prest-O-Lite Service, operating through forty plants
and warehouses, places Prest-O-Lite Dissolved Acetylene at

the command of ship-yards anywhere, at any time and in any

yevvad ~[ Produce!

NE hundred and forty-four years ago Lavoisier coined the
name Oxygen.

In choosing the Greek word I'evviw “I produce,” as
his main root he had in mind a chemical reaction commonly asso-
ciated with the gas.

Had Lavoisier been able to foresee the tremendous part that Linde
Oxygen is playing in modern industrial development, he would have
realized the vast significance of that word [‘evvaw “I produce!”

The country over, Linde Oxygen is daily making possible greater

production—everywhere it is saving time and cutting costs.

5s CHARACTER #'CRAF TSMANSHIP= SERVICE®

Quick turn-around in port is
dependent on many factors, not
least the character of the ship
herself. Freedom from costly,
time-wasting repairs, and ade-
quate cargo-handling and fuel-
ing facilities are but two meas-
ures of this character. Records
of years of continuous opera-
tion of cargo carriers and liners
built by New York Ship have
demonstrated that these ships
invariably possess those quali-
ties and all others which assure
economy of operation.

RY WT
oN

Proper design of hull and power plant,
craftsmanship in the carrying out of those
designs, assure satisfactory economical per-
formance at sea. Ships that stand up under
hard-driving service year after year; that
are fast where speed is needed, and low
in fuel consumption; ships that meet the
individual requirements of their trade; are
the ships that are profitable under condi-
tions of keen competition. Such are the
ships that are built at New York Ship.

ducing action takes place on

by removing a portion of the blade.

Wear on this surface, because of the
complete reversal, does not alter the
entrance or exit angle of the steam. Therefore, the action of the
steam will remain the same as when the turbine was new, which
means that the efficiency will like-wise remain unaltered.

Tubes Are Cold-Drawn to Size and Gauge

Wheeler Crescent Brand Tubes are cold-drawn to specified
dimensions on powerful benches designed to draw the metal slowly
and steadily through highly polished steel dies. On the inside of
the tube is a polished steel plug on a rod which is so placed within
the die as to prevent the tube from collapsing while it is being
worked to the required dimensions.

All Annealing is Under Expert Supervision

After each cold-drawing operation, the metal is annealed in order
to recrystallize it and remove distortion caused by the strain. This

ing pyrometers and by recording instruments, thereby maintaining an
accurate check on heat treatment of materials during the process
of manufacture, as well as of the finished product.

Annealing is very exacting and requires constant supervision
At the Wheeler Tube Mill, annealing is done by men long associated
in the wrought brass business.

Finally Tested to 1,000-Pounds Pressure

After Wheeler Crescent Brand Tubes are finished and cut to
required lengths, they are passed to a testing machine wherein

each tube is subjected to a hydraulic pressure of 1,000 pounds
per square inch.

Any defect developed during the manufacture of tubes may
become apparent under this test, and every faulty tube is rejected.

This severe pressure test demonstrates
the necessity of all the care which we ex-
ercise in selecting materials, in casting, in

Cuts Rust

Reduce the Cost
of Removing Rust

When your shell plates are punched far in advance of the erection
schedule and lie in the plate racks, exposed to rain and snow, they
rust. That rust must be removed in way of the side frames, butts
and laps.

Chippers will clean the plates. But the cost per ton will be
tremendous.

Paint those plates with Rustsolvo first. The work of the chipper
will be reduced fifty per cent—and your cost will decrease pro-
portionately. .

Rustsolvo softens rust, red or white lead, paint, tar, grease or dirt.
It is a harmless, free flowing, non-inflammable liquid. It works
quickly and without injury to metal, rubber or wood.

turned by a child. An application before making port 4
perfect operation.

For Rustsolvo is the liquid that cuts rust. In like manner, tt?

\usTsOLVO

Reduce the Cost
of Removing Rust

When your shell plates are punched far in advance of the erection
schedule and lie in the plate racks, exposed to rain and snow, they
rust. That rust must be removed in way of the side frames, butts

and laps.
Chippers will clean the plates. But the cost per ton will be

tremendous.

Paint those plates with Rustsolvo first. The work of the chipper
will be reduced fifty per cent—and your cost will decrease pro-
portionately.

Rustsolvo softens rust, red or white lead, paint, tar, grease or dirt.
It is a harmless, free flowing, non-inflammable liquid. It works
quickly and without injury to metal, rubber or wood.

Order Rustsolvo now and try it on those rusty plates and bolts.
Satisfaction guaranteed or money refunded.

If your ship chandler does not have
Rustsolvo in stock, send your orders

of Scotch Marine Boiler bank in Foster Marine Water-tube Boiler

Superheat is rapidly becoming standard practice in the merchant marine
as it enables the steam prime mover to increase its efficiency at the minimum
expense in first cost and upkeep cost.

Over fifty percent of all American steamships in foreign trade are fitted
with superheaters. [he major portion of these develop a superheat of 50

fr 7/5)® JB,

This amount of superheat can be used in triple expansion engines with-
out oil for lubrication of cylinder walls. A moderate amount of superheat is
also sufficient to overcome the priming that occurs with all types of boilers
when heavily salted.

Foster Marine Superheaters are used in over seventy-five percent of the
American ships equipped with superheaters. [hey are of the well known
Foster Extended Surface type similar to the recognized standard in land
plants. Their rugged construction is especially suitable for marine use where
conditions are much more severe than in locomotive or stationary work.

PIPE THAT
| BENDS WELL

—an important requirement
in the shipyard

PRE unusual ductility of “NATIONAL”

Pipe gives a bend with minimum distor-
tion of cross-section and free from objection-

able buckling.

The high tensile strength and sound welds
maintain the required bursting strength of the
pipe after it has been subjected to the severe
stretching and compressive stresses of bending
and flanging, while the elasticity remains
amply high for absorbing the service stresses
for which the bend may be designed.

Because of these factors, “NATIONAL”
Pipe for bending and flanging purposes is
exceptionally able to meet the requirements
of the shipbuilding engineer.

sectioned showing:

1 Train of sturdy stub-tooth gears.
Made of special alloy steel. Transmits
uninterrupted power to the drill spindle.
No lost motion due to over-travel or
slippage. 33% faster than drives of
the ratchet type.

2 Thrust ball bearing carries feed
screw pressure. Note spindle gear
forged integral with spindle.

3 Roller bearings support gear train.
Ample provision for thorough lubrica-
tion of working parts by means of
‘*splash’’ system.

4 One-piece, solid forged steel crank-
shaft, having two throws with Pins at
go degrees. Crankshaft is of ample
proportions and strength throughout.

5 Crossheads prevent side wear of
cylinder walls and pistons. This con-
struction parallels high-grade steam
engine practice, insuring permanent
alignment and long life of reciprocating
parts.

6 Balanced piston valves fitted so that
only room for the oil film is allowed.
Provides a near perfect seal and re-
quires the minimum of power to operate.
Result—long life of parts and highest
economy.

7 Thevalve pistons operate in replace-
able, long-wearing bronze bushings, in-
suring long service and low upkeep cost.

8 The sturdy forged steel toggles and
connecting rods are capable of with-
standing the severest service.

9 The pistons are machined from solid
stock, heat treated and ground to size,
resulting in longest wear.

10 Standard Little Giant throttle con-
trol permits ease of operation with
consequentincreased production. Little
Giant is the only close-quarters air
drill which can be reversed from the
throttle.

Pride
of France
Saves Oil with a

DE LAVAL
Oil Purifier

HE S. S. Paris, of the French line, is the

largest and most luxurious vessel ever con-
structed in France. Her builders have gone
the limit to make her the last word in design,
construction and operation. Naturally they
have a De Laval Oil Purifier aboard to remove
water and dirt from her lubricating oil and
keep her turbine bearings in perfect condition.

Po The De Laval Oil Purifier on the Paris does two things:
| First, it gives her machinery longer life and lessens bearing
troubles by keeping clean oil in the system at all times. Sec-
ond, it obviates the necessity for ever pumping oil overboard
| and so materially reduces the cost of lubrication. Just this last
; feature of De Laval performance will pay for installing a ma-
fee chine within a short time. The De Laval Oil Purifier is simple
ie in operation and positive in action. Strong centrifugal force
| removes impurities from the oil in heavy seas, as well as when
the ship is in port.

De Laval Bulletins Nos. 102 and 103 give further interesting
information. They are yours for the asking.

The final cost of a marine boiler is affected by many
factors, among which are first cost, fuel cost for steam
produced, cleaning and repairing costs, useful life of
boiler, and cost of any delay of ship due to boiler
repairs, renewals, etc.

It is seldom true that the cheapest in first cost is
also the cheapest in final cost, but this is a fact when
comparing marine boilers. of the Scotch and water-tube
types. Not only is the more modern and efficient
water-tube boiler operating on present-day steam pres-
sures less expensive in first cost than on Scotch boil-
ers of equal capacity, but its repair cost is less, and it

Cost—The Deciding Factor For All Boilers

eliminates the renewal cost required by the short-lived
Scotch type. The smaller weight of water-tube boilers
results in a larger cargo-carrying and profit-earning
Capacity, the reduction of which with Scotch boilers
should be taken into consideration when determining
the final cost of marine boilers.

The first cost of Foster Boilers is not only less than
that of similar sized Scotch boilers but the other fac-
tors that affect final cost are also less where Foster
Boilers are used. :

The reason for the low Foster Boiler costs can be
readily obtained from our catalog.

Parts of the ship that need extra
care in painting

If this picture were in colors there
would be red streaks at the places
where plates lap.

It is particularly important that
contact surfaces be well painted
with red-lead before assembly, and
that all joints, rivet heads, etc., get
an extra coat before the finishing
coats are put on.

Ship owners and operators are
pretty well agreed that the whole
hull should have at least two coats
of red-lead, inside and out, regard-
less of the nature of the final cover-
ing.

They know that red-lead adds
years to the useful life of a ship.

SOOT REMOVAL FROM SCOTCH

MARINE BOILERS

is effectively accomplished by the improved Diamond Rear End Blower
(Model B).

And soot removal is essential to economy. Power is one of the largest
items of expense in the cost of operating a vessel, and the cost of fuel
represents on the average 70 per cent. of the cost of power. The pres-
ence of soot has cost—it still costs—a loss of hundreds of thousands of
tons of coal and hundreds of thusands of barrels of fuel oil a year to ship
owners. Soot waste has been eliminated on many ships, and it can be
eliminated on all with a consequent notable increase in boiler efficiency
and a consequent great increase in marine profits.

Method of installing Model B blowers
Thousands of Diamond Model B Blowers are in use today on Scotch on a three-furnace Scotch boiler.

Marine boiler. The blower is permanently installed through the rear
water leg, a hole being cut in the plates and a section of tubing expanded
and beaded into place. The blower is encased in this tubing. When not
in use the blower is secreted in the casing. As the steam is turned on
the nozzle is automatically forced forward into blowing position. In
operation dry steam is shot into each tube with the draft at a terrific
velocity, sweeping and scouring the soot from the full length of the tubes.
Diamond Soot Blowers save fuel and labor. Write for full information on blowers for

any type of boiler, requesting your copy of Bulletin 134, ‘How Some Ship Owners Have
Increased Their Profits.’

The World’s First Diesel-Electric Cargo Ship

HE reliability and efficiency of Diesel engine-electric
drive will soon be further demonstrated on the 2,200
dead weight ton ‘‘Fordonian” to be the world’s first
Diesel-electric cargo ship, now having its Diesel-direct
drive replaced by Diesel-electric drive at the Tebo Yacht
Basin of the Todd Shipyards Corporation.

The General Electric Company with its many years ex-
perience in the marine field was the first to successfully
apply Diesel-electric propulsion to ships. The electric
@quipment for the 150-foot fishing trawler ‘‘Mariner”
was furnished by this Company and has been in service
since February, 1920.

Diesel engine-electric drive with G-E electric equipment
was chosen for the ‘“‘Fordonian”’ because of its highoverall
economy, saving in hull space, ease and flexibility of
control, and reliability.

The General Electric Company supplies generating and
control apparatus, propulsion motors, and motors for
engine room and deck auxiliaries of every kind for Diesel-

Calno—Sirocco Equipped

VENTILATING THE
MODERN SHIP

The need for right ventilation on ship-board is
more apparent todey than ever before.

On the freighter, the cargo must have a depend-
able supply of fresh air—interior chambers must be
dried and kept dry, gases and vapors from bulk or
package goods must be removed. ,

On the passenger boat the comfort and health of
passengers means that a dependable system of ven-
tilation must be at hand—whether at the dock or
at sea.

Climatic changes on the sea-going vessel, to
which all ships are subject, demand forced and
positive ventilation for the sake of quality of the
cargo or comfort of the passengers.

TRADE MARK.

Sirocco fans, blowers and air-washers furnish this
dependable ventilation for any type of boat. Aside
from ventilation, “A B C” engines are used to op-
erate the “Sirocco” forced draft fans for boilers.

This whole subject of ventilation is covered in
our booklet “A B C Equipment for Ships.” A copy
will be sent you on request.

Will Your Condenser Tubes

Season Crack?
Try These Tests

Flattening Test Cut off a section about 4 inches long from a con-

: denser tube. Hammer flat one end of it, then ham-
mer the opposite end. If the metal cracks, it indicates a defect or else extreme
hardness. Hard drawn tubing is usually associated with season cracking.

Accelerated Corrosion Test "me 2 small section of

tubing for 15 minutes in a 10
per cent solution of mercurous nitrate solution. If severe strains are present in the
metal, the tube will crack in a manner similar to season cracking. This test was
used by the United States government in testing 75 mm. brass shrapnel cases to
determine whether they would deteriorate in storage. We will be pleased to furnish
full directions for making up this: solution.

Scovill Tubing

is a product based on knowl-
edge acquired after a century
of brass making. Owing to the
fact that it has been relieved
from drawing strains, it will
not season crack. Furthermore
its extremely fine grain offers
greater resistance to corrosion,
resulting in longer life. It pays
to buy condenser tubes on the
basis of length of service rather : : d

Watertube Boiler conducted by
a Board of U. S. Naval Engineers
established this record. The corre-

There are two points to bear in mind
in this connection—

(1) that this efficiency is due
largely to the excellent design
and construction of structural
parts and assembly of the
Ward Boiler—and

(2) that all Ward Boilers are built
alike and any one of them can

The Typical Maag Tooth

For Strength— Use the Gear
With the Strongest Tooth

Maag Gears are strong where strength counts most.
At the base of the teeth where the ordinary pinion
is often weakest, Maag teeth are always strongest.
This feature of Maag Gear design distinguishes them
from other gears. The extra metal—see diagrams in
circle below—placed at the point of greatest stress
increases the margin of safety. It assures freedom
from tooth breakage. It keeps Maag gears on the
job under conditions that cut short the life of
ordinary gears.

You need strong, slow feet in diameter and in

Better Than The Law Demands

A ship wireless equipment may meet the
requirements of the law, and yet it may be
ten years behind the radio times.

The set which is installed on a ship by the
Radio Corporation of America always embodies
the highest engineering skill. It is far more ef-
ficient than the law demands—far more trust-
worthy. It is the result of the systematic

development of wireless by the Radio Cor-
poration of America over a period of twenty

years.

Thousands of vessels are now equipped with
the efficient apparatus of the Radio Corpora-

tion of America—apparatus which is better
than the law demands.

The sets of the Radio Corporation of America
are the most efficient that scientific skill can
produce. For behind the Radio Corporation of
America stand the splendidly equipped Re-
search Laboratories of the General Electric
Company, The American Telephone & Tele-
graph Company and The Western Electric
Company, where, year in and year out, eminent
physicists conduct investigations that result in
new radio advances. No other company enjoys
the benefit of this scientific research in the field
of radio communication.

| An Efficient Pipe
Covering Should
Not be Heavy

Every ounce of weight beyond that
really necessary for structural strength
is a detriment and is likely to induce
sagging.

Some well known pipe coverings weigh
from 18 to 42 pounds per cubic foot.
85% Magnesia Pipe and Boiler Covering
weighs approximately 12 pounds per
cubic foot, and yet its crushing strength

may be conservatively rated at 100 pounds
to the square inch of standard thickness!
A heavy man can stand on a half section
of 85% Magnesia Pipe Covering, placed
flat and unsupported on the floor, without
crushing it.

It would be easy to make 85% Mag-
nesia of greater structural strength and
greater weight, if that were desirable.

Only 15 per cent. of asbestos fibre is Magnesia Association of America

used. The result is a happy combination

of necessary strength with lightness and 753 Bulletin Bldg., Philadelphia, Pa.

vessels off the Virginia Capes and we can
imagine no more severe test than this.”

Now They Have Four “C-O”

Examination by the microscope reveals the nature
of the grain structure and readily determines im-

cate the existing weakness but at present there is
no definite relation between the grain structure of
a weld and its tensile properties, making therefore
comparative tests essential.

For comparative efficiency of Weld to parent or
base metal it is necessary to apply the same test
methods to the welded joint as to the plate itself.

The resilient deep corrugation in

You use large turnbuckles for temporary
fastenings in the construction of ships and
when making repairs. Each time a turn=
buckle is used the workman must find a
wrench or bar with which to turn the buckle.
How much time does that workman lose
while hunting that wrench or bar?

When the turnbuckle must be loosened the
same proceedure must be used. More time Jost.

FIRE

The most dreaded peril of the sea

—takes annually its toll of human lives. 2% of lives lost
at sea are caused by fire. 7% of all casualties are due to fire.
In the World War only 4.5% died from wounds.

—destroys millions of dollars worth of property needed by
the people of the world. One-seventh of all property lost
at sea is lost on account of fire.

—causes untold losses on account of delays, inconvenience to
shippers and consignees, with consequent loss of faith and
good will. The shipowner and operator bear the brunt of
this loss. Insurance does not pay for this.

—increases operating expenses through higher insurance
premiums.

The greatest fire hazard is in holds and closed compartments.

SAFE T Y

may be secured by the

RICH SMOKE SYSTEM

Detects, locates and extinguishes fires in the holds and closed
compartments, utilizing the steam smothering lines required
by Federal Law.

\V/ESING Marine Engine Oil — for
thrust bearing and reciprocating en-
gine lubrication—is the latest develop-
ment among the Sun Marine Oils. It
conforms in efficiency with the high stand-
ards maintained for years in the famous

Sun XX Marine Oil.

Viking Engine Oil, by reason of a
special patented refining process, will form
a perfect and lasting emulsion with either
salt or fresh water.

The body of this emulsion may be
varied from a heavy pastelike substance
to any consistency by the simple addition
of a larger percentage of water.

For lubrication of thrust bearings an
emulsion of Viking Oil with from 50 to
75 per cent water is recommended.

Viking Marine Engine Oil

of oils highly compounded with blown
rape seed, Viking Marine Engine Oil
will not. deteriorate and become rancid
with age.

The Sun Company is one of the
world’s largest producers, refiners and
shippers of petroleum products. Its out-
put of lubricating oils alone exceeds a
million and a half gallons per week.

The choice of a lubricant for any par-
ticular purpose demands expert advice.
Engineers of the Sun Company are avail-
able to make an analysis of your lubrica-
tion requirements and specify the right

ia ee ee |
icici

Although having the saponifiable value oils to meet them. This service is free.

"Safety at Sea”

STEWARD BOAT RELEASING

Approved by U. S. Steamboat Inspection Service
British Board of Trade and Requirements
of Other Governments

PATENTED IN U. S. A. AND FOREIGN COUNTRIES

READILY INSTALLED IN

To operate the Steward Boat Releasing Gear a single
lever is thrown over, revolving the shaft and releasing
in less than a half turn. There are no chains, wires or
thin bars in tension or compression; accidental release is

impossible.

The action is positive and can only be done with delibera-
tion, but is so simple that in emergency any one can safely
release a lifeboat full of people. The leverage is so
powerful that very little effort is required even when the
boat is not waterborne.

Detail of Operation

NEW OR OLD BOATS

The falls may be instantly attached to the hooks with-
out moving the lever and cannot drop out when slack;
they may be disengaged just as readily if desired.

It has been the experience of practical seamen that the
Steward Releasing Gear solves the problem of clearing
away a boat in a seaway. No matter how high the sea
you can release both ends instantly when the word is

passed. One turn of the lever and the boat is afloat.

ACHINING operations are an impor-

tant item of production cost which
is materially reduced where Shepard Elec-
tric Hoists are installed.

The operator of a Shepard waives assistance,
for he has in his control all necessary equip-
ment for handling the heavy pieces and plac-
ing them in the precise position.

“Shepards” do the work rapidly and are
economical in operation and maintenance.
If you have anything to be picked up, car-
ried, and put down, give it to a Shepard, for
in so doing you are providing efficient, de-
pendable, and profitable means for doing the
work.

HE oxy-acetylene welding and cutting torches —
those twin metal surgeons—are indispensable in

ship yards.

Wherever metals must be cut or joined neatly,
quickly and economically the oxy-acetylene process is
invaluable.

DISSOLVED ACETYLENE

because of its portability, has made it possible to
weld or cut in the most inaccessible places. Wherever
the job may be—below or aloft, inside or out—Prest-

These ideals have been steadfastly maintained; and upon the foundation of complete
plant facilities and modern steel-working practice there has grown up a tradition of accom-

American Merchant Marine, that reflect New York Ship’s

The finest equipment in the world cannot run indefinitely
without attention or repair. While every precaution and care
1s taken in the design and construction of Terry Turbines to
make them long-lived and fool-proof, there is still the pos-
sibility that repairs or spare parts may be necessary. The
unusual accessibility of Terry Turbines would be useless with-
outa well maintained stock room from which repair part orders
may be immediately filled. The interchangeability of those
spare parts is further insurance against prolonged shutdowns.

Information on $20,761,000 in
New Marine Work Presented
During Exposition Week

HAT are naval architects, consulting engineers, shipbuilders

and ship repair men and ship and pier equipment men most
vitally interested in at the present moment? In the light of present
conditions this question may be answered by the one word—
“Contracts.”

With this subject in mind it may be interesting to know that
MARINE ENGINEERING AND SHIPPING AGE in its daily edition pub-
lished during the exposition presented to its advertisers and gen-
eral readers advance information of new vessel construction, repair
work, and port and pier developments having a total estimated valu-
ation of more than $20,761,000. And, mind you, this vast sum of
money appertains to contracts for all classes of maritime work which
have not yet been placed!

We call attention to these facts and figures to back our contention
that MARINE ENGINEERING AND SHIPPING AGE provides the only
top-notch service to its advertisers and we take the opportunity of
asking this question: “Can you afford to be without such a service—
a service which has so vital a bearing on your actual business
interests?”

It is upon such a foundation that we base our claim that MARINE
ENGINEERING AND SHIPPING AGE’S Weekly Bulletin and monthly
magazine are without equal in the marine field. After the close of
the exposition, the Weekly Bulletin of Advance Information was
resumed as heretofore, and the December number of the magazine
will contain articles which were precluded from publication in the
Daily Bulletin because of lack of space.

Comparison of our weekly and monthly publications with any
other in the field 1s invited; we are sparing no time or effort to pro-
vide a worth while service to our advertisers and if you will take
the time to look over the situation we have no fear as to what your
decision will be.

RUSTSOLVO

The product that is destined to save billions
of dollars yearly in connection with metal re-
pair work in Shipbuilding and Repair Yards,
on Board Ship, Railroads, Automobiles and

Trucks, Farm Machinery, Plumbing and Con-

struction Work, etc.

When Overhauling
the Propeller

Rigidly bolted propellers of the built-up type can be
easily taken apart without breakage by using Rustsolvo.

Where blades, bolts and nuts are solidly united by
corrosion, a small quantity of Rustsolvo properly ap-
plied will seep right through and free every frozen or
corroded part, which can then be loosened without
force or breakage.

Think of the tremendous saving of material. “Think
how quickly the work can be done, and the amount
of time saved.

By the use of Rustsolvo, the problem of rust in pro-
peller repairs is solved.

Rustsolvo is a scientific solvent in liquid form which,
when applied to rusted joints, bolts and nuts, quickly
frees these parts, permitting their quick removal with-
out destruction of material.

Rustsolvo is a non-inflammable liquid that cuts alike
rust, red or white lead, paint, tar or dirt.

It comes to you in handy containers ready for instant
use.

That it does what we claim for it is evidenced by the
constantly growing list of users.

We guarantee satisfaction or money refunded.

If not already in stock. send your order direct to us.

Each gallon of RUSTSOLVO rightly used, will
produce savings in time, labor and materials from
$300.00 to $1,000.00 and over.

Cuts Rust

Eliminates the Problem

of Odd Bolts

Odd rivets are the ever present drag in lowering your
riveting costs. Try as you will, they seem to appear
in every part of the ship. And what a saving you
would realize if you could eliminate this evil.

The chief cause is rust bound bolts. No piece work
riveter will stop to bother with a bolt if it does not
respond to his first attempt to loosen it. If it is frozen
with rust, he passes by.

But if the riveter had with him the means of loosening
that bolt with no effort on his part, the results would
be different.

It lies within your power to supply him with this means.
Rustsolvo is a liquid which cuts rust. A few drops
applied to a rust bound bolt and a child can loosen it.
Equipped with a small can of Rustsolvo, the riveter
would have no cause to leave a trail of rust tight bolts

behind him.

Where Strength means Safety

When a man buys Whitlock Manila Rope he purchases more than
simply first-class cordage—he buys protection, safety insurance for
his life and property. And he gets it. For Whitlock Rope stands
up manfully under the hardest work.

WAITLOCK CORDAGE

THE UTMOST IN ROPE VALUE

By its superior service, Whitlock Rope creates a great goodwill in favour of the
dealer who supplies it. And, fortunately for the user of rope, even the first cost of
Whitlock is less, for it has greater length per pound. Naturally, progressive dealers
throughout the country are building business with Whitlock Guaranteed Cordage.

Whitlock Manila is the rope that is guaranteed superior to U.S. Government
Specifications not only in strength and length per pound, but also in quality of fiber.
If you are a user of rope, Whitlock can save you money; if you are a dealer, it
can make more money for you.

Write today for our 1921 Catalog which tells the complete story of Whitlock
Manila and Sisal products. And ask for the Whitlock distributor or dealer in
your vicinity. a:

WHEELER STEAM JET AIR PUMPS

Maintain High Vacuum Efficiently Without
Complicated and Expensive Accessories

N the Wheeler Steam Jet Air Pump the
inter-condenser between the two jets
condenses the steam in the air-steam

mixture from the first jet, reducing the
volume to be entrained in the second stage
jet. This reduces steam consumption to
one-half that needed if no inter-condenser
is used.

In the combined inter-condenser and
heater type, here illustrated, condensate
from the main condenser circulates
through the inter-condenser and a heater
recelving the discharge of the second jet,
thus absorbing practically all of the heat of
the actuated steam from the mixtures dis-
charged by both jets. No air separating
chamber is required and air is not intro-
duced into the condensate or feed water.

Other features of this type are:

The increasing use of superheat
in the marine field

The cost of marine fuel has increased in the last few
years to a point where it is receiving considerable atten-
tion. ‘Io improve the fuel economy of marine propel-
ling equipment, water-tube boilers, turbines, and high
vacuum equipment have been installed, on many ships,
and over one thousand ships have been fitted with super-
heaters.

The fuel consumption of an existing installation can
be reduced at less expense by adding superheaters than
by any other method, and the fuel saving effected by
Foster Superheaters is greater than obtained from high
priced, high grade equipment of other types. In many
cases the cost of Foster Superheaters has been saved in
from two to three years’ operation. ‘This is particularly
true in the case of Scotch marine boilers, where the super-
heat can be obtained from the waste gases without any
additional fuel being burned.

In a very recent case a large tow boat company
HostocmSunerheateumine checked the performance of two duplicate tugs, one with
stalled in uptake of and the other without Foster waste heat type superheaters.
Scotch Boiler The fuel saving of 20% is paying for the superheaters

in less than two years.

In many Scotch boilers the steam space is small and
when the boilers are salted severe priming occurs, causing
rapid wearing of turbine blades or short life of engine
piston rings. Foster waste heat superheaters entirely elimi-
nate this trouble and save considerable in turbine or engine
repairs. This also prevents delays in the ships’ operation,
which results in a very attractive additional saving.

Superheat has become standard in land
plants and at the present rate of progress will
be standard in marine plants in the next few
years. If America is to keep her place on
the seas her ships must follow the proven
economy of her land plants. The American
stationary plants are admitted the peer of all
others and the American marine plants will
unquestionably win the same prestige when
advantage is taken of known successful fuel
saving methods.

A coat of armor against rust

Men that own and operate ships are large users of
Dutch Boy Red-Lead —the tough, elastic, waterproof
paint that protects metal surfaces from rust.

The U. S. Navy, for instance, uses red-lead on all its
vessels for almost every metal surface, because it with-
stands the action of salt water and preserves the steel.

Dutch Boy Red-Lead has the added advantage of
greater spreading power than other paints for marine
use. It gives a coat of uniform thickness and tough-
ness, and won’t chip, peel, or scale.

Dutch Boy Red-Lead does not harden in the pail.
That means no red-lead wasted. No time lost.

Specify Dutch Boy Red-Lead for all metal surfaces,
paste or liquid form. Can be tinted to your require-
ments for finishing coats.
